True Familiar

Sacrifice some your life to create a new one. This spell will make it impossible for you to use any other conjuration spell below 4th level. Summon a creature from find familiar list (if your a pack of chain warlock then that includes the extra summons you get). This familiar can never change but will get stronger the longer it's alive (if lower then your level, Ex. familiar is Lv.1 but Caster is Lv.3 then every kill the familiar gets will level it up by one level until it matches the casters Level) Each Level the Familiar gets 1 HP dice equal (look at creature stat block to know which dice) they also get feats/ASI at the same level as fighters (Lv.4,6,8,12,14,16,19). The creature gets a bonus to saving throws, Attack rolls, and Damage rolls equal to your spellcasting ability as well as a bonus to their corresponding stat equal to your proficiency bonus to a maximum of 22(Ex. Caster is a Lv.4 warlock who uses a skeleton, the skeletons charisma goes from 5 to 7). If the creature can use equipment/armor then you can replace it but once given to the familiar it will always stay on them until they die at which point the equipment will be destroyed. If the familiar is killed then you can't use this spell again for 1 month or until you level up. If the familiar is killed you regain access to all conjuration spells and can chose a different familiar if you re-use this spell. The creatures level will equal the level of the spell slot used to summon them.
